My opponent has 3 creatures in his graveyard, I have 1 creature in mine. My opponents casts Exhume in response I cast Return to Nature. My question is, does Exhume target? Can I wait till my opponent chooses a creature and in response I cast Return to Nature and exile the card he/she is trying to return to the battlefield?
Exhume does not target. You can tell from it not using the word "target" anywhere on its text.
Each player chooses the creature to be returned as Exhume resolves, not beforehand. You don't know which creature they're "trying to return" until they actually return it.
The best you can do with Return to Nature is to exile the strongest of the three cards on their graveyard so your opponent only gets the second best, but they still get a creature.
